Well, you can't run DDL during pg_upgrade either. I've never seen a
solution that supported that, and if it did, it would certainly violate the
"simple" rule you advocate.

Simplicity is key, I agree. But that's just a user interface feature, not a
comment on what's underneath the covers. pg_upgrade is not simple and is
never likely to be so, under the covers.

Anyway, I'm cool if you don't want to use it, for while or never. Options
are good.
